We realized that two patches I submitted in December (and now applied
to cryptodev-2.6) are needed to avoid a null pointer dereference
when loading the qat driver on some specific c62x devices:
841d6d10b38a2508c640ce: crypto: qat - zero esram only for DH85x devices
4f78ce870a4da0cf4db265: crypto: qat - fix bar discovery for c62x
This problem was introduced in 4.5 when we sent the c62x driver and
we recommend it should go to the stable kernels, 4.8.17 and 4.9.6.
Should I re-send these two patches to stable after they are merged
in Linus’ tree?
Thanks,

Giovanni
